This may be what Bp. Sheen referred to as the "Apostolate of Beauty" and why the Cure of Ars said to keep a clean face.
One of my favorite conversion stories!
This has been an encouragement, thanks for posting it.
**I caught sight of him on his knees, in the chapel of St. Michael the Archangel . I went up to him and touched him. I had to do this three or four times before he became aware of my presence. Finally he turned towards me, face bathed in tears...with an expression no words can describe...he took hold of his Miraculous Medal and kissed it with passionate emotion. He broke into tears at the thought of all the heretics and unbelievers....Gradually this delirious emotion subsided and he grew calmer, and now his face was radiant, almost transfigured. He begged me to take him to a priest and asked when he could receive holy Baptism, for now he was sure he could not live without it.**
Wow, what a story — and that is just the beginning of it!
